Hazards

A new study has comprehensively mapped the immediate after effects of the January 2022 eruption of Hunga Tonga - Hunga Ha’apai, highlighting the risks of similar events.

This project aims to establish connections between weather and river flow forecasting, inundation prediction and risks to people and assets.

NIWA's coastal hazards research is improving knowledge and providing tools to help understand coastal hazards and potential impacts for Aotearoa New Zealand – both now and in the future as sea levels continue to rise.

On this page, you can find information about tide forecasts, sea-level network, tidal model of New Zealand's EEZ, and red-alert days for coastal flooding.

NIWA's Tide forecaster provides tidal data for any point in New Zealand.

Cam-Era is a network of computer-controlled cameras that monitor the New Zealand environment for research and resource management. These are also useful for surfers and swimmers.

A newly launched tool developed by NIWA and the Ministry for Primary Industries (MPI) to predict dryness and drought will help farmers and growers be better prepared for challenging weather conditions.

NIWA plays a pivotal role in weather hazards research, providing critical information and tools for assessing, monitoring, and managing weather-related risks and impacts.

NIWA studies marine geological hazards, including earthquakes, submarine landslides and tsunami, volcanic eruptions, seafloor scour, sediment transport and shallow gas.
